Abstract

The article presents the results of an experiment (2016—2019) to study the influence of humic preparation on the effectiveness of insecticides of various chemical classes. Phytosanitary monitoring, pests count before and after treatment were carried out in addition to calculating the biological efficiency of insecticides; the impact on chickpea productivity and nutrition regimen was considered against the background of the chemical protection system with the inclusion of the humic preparation BIO-Don10. Harmful objects are cotton budworm (Helicovera armigera Hb) and bean aphid (Aphis fabae). It was found that the pyrethroid class preparation is more effective against cotton scoop. The reduction in bean damage is 93.7%. The efficiency of organophosphorus compounds does not exceed 45.0% in view of the developed stability. The preparations under study showed high efficiency against bean aphid, the decrease in aphid numbers is 93.9 and 90.9% respectively. Humic preparation did not affect this indicator, but allowed to increase the saved crop on the option with pyrethroid by 46.4 - 56.0%, with dimethoate by 29.6 - 40.0%.

Highlights

  • The Rostov oblast is in demand of leguminous crops

  • In the natural and climatic conditions of the Rostov oblast, cotton budworm develops in one generation

  • Chickpea crops are settled by cotton budworm in 7-10 days in the budding phase and this occurs unevenly

Summary

Introduction

The Rostov oblast is in demand of leguminous crops. They occupy 8.7% in the structure of Russia's acreage, which stands for 74 thousand hectares. The severity of the first on chickpea is such that it is possible to lose the entire crop due to grain damage [1]. Another pest is sucking out cell sap and by that is able to cause damage and epinasty of plant shoots; as a result, there is a development delay and a productivity decrease. Insecticide use carries a risk of suppressing plant growth and development due to toxicological load, to which legumes are extremely sensitive. At the same time, including elements in the agro-ecosystem that ensure plant growth, as well as increasing the intensity of microbiological and physico-chemical processes in soil [4]
